What is claimed is: 1. A flow-controlled dispensing container fillable with a liquid, the container comprising: a squeezable reservoir for holding the liquid prior to dispensing; a dispensing head that appears substantially flat in profile wherein the head is integral with the sgueezable reservoir and wherein the head has a distal end and a proximal end; an outlet that is interconnected with the reservoir by a passage at an inlet and wherein the outlet is at the distal end of the dispensing head and the inlet is at the proximal end, wherein the outlet is sealed with a breakable seal which reveals the outlet when broken; a stop disposed near the proximal end of the dispensing head to prevent over-insertion of the dispensing head into a user's mouth when the container is used to dispense the liquid to the user; and a flow control system comprising the inlet to the passage, the passage, and the outlet that dispenses the liquid at a desired outlet velocity and within a desired delivery time when the squeezable reservoir is squeezed, wherein the flow control system comprises a single inlet with a cross-section area sufficient to retain fluid in the reservoir by action of surface tension, and having two passages each having a semi-circular path through the dispensing head and discharging through a single outlet which has a cross-section area sufficient to retain fluid in the passage by action of surface tension of the liquid when the breakable seal is broken, wherein the cross-section areas, lengths, and surface roughness of the inlet, outlet and passage are designed to act together to control the outlet velocity and delivery time of the discharged liquid. 2. The dispensing container according to claim 1, wherein the dispensing container is unitary. 3. The dispensing container according to claim 1, wherein the desired outlet velocity is within a range of from about 2 m/s to about 15 m/s. 4. The dispensing container according to claim 1, wherein the desired outlet velocity is within a range of from about 5 m/s to about 10 m/s. 5. The dispensing container according to claim 1, wherein the desired delivery time is within a range of from about 0.5 sec. to about 4 sec. 6. The dispensing container according to claim 1, wherein the desired delivery time is within a range of from about 1 sec. to about 2 sec. 7. The dispensing container according to claim 1, wherein said passage comprises multiple passages. 8. The dispensing container according to claim 1, wherein said passage has a rippling undulating shape. 9. The dispensing container according to claim 1, wherein said passage has a serpentine shape. 10. The dispensing container according to claim 1, wherein said passage comprises a maze. 11. The dispensing container according to claim 1, wherein the dispensing head has a bottom surface and a top surface one or both of which has an indented portion. 12. The dispensing container according to claim 1, wherein the top surface and the bottom surface of the dispensing head have matching indented portions that define the shape of the passage that interconnects the squeezable reservoir and the outlet. 13. The dispensing container according to claim 12, wherein the matching indented portions define the shape of the passage that interconnects the squeezable reservoir and the outlet as a single channel interconnecting the squeezable reservoir and the outlet, where the channel is flanked on either side by a curved portion forming a side of the dispensing head and having rounded edges. 14. The dispensing container according to claim 1, wherein the breakable seal is integral with a tab which is designed for gripping between the thumb and forefinger for the purpose of breaking the seal. 15. The dispensing container according to claim 1, further comprising a substantially flat tail disposed from the reservoir opposite the dispensing head and in a plane that is substantially parallel to the plane of the dispensing head. 16. The dispensing container according to claim 1, further comprising a liquid in the squeezable reservoir. 17. The dispensing container according to claim 16, wherein the liquid comprises at least one material that is selected from vitamins, over-the-counter drugs, or prescription drugs.
